Android - Disabling enter key press for a text editor

//A bug where hitting enter after entering text in a EditText box would clear the box
//the code below prevents this
//disable enter key press
EditText txtEdit = (EditText)view.findViewById(R.id.text_input);
txtEdit.setOnEditorActionListener(new OnEditorActionListener() {
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (event != null&& (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
InputMethodManager in = (InputMethodManager) v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
in.hideSoftInputFromWindow(v.getApplicationWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
return true;
}
return false;
}
});

Disabling dates in JQueryUI Datepicker - hooked up to an MVC 3 controller action to provide dates.

//method in controller to return list of dates.
public ActionResult GetDisabledDates(string id) {
//get list of dates separated by comma ...
return Json(new {disabledDatesArray = result }, JsonRequestBehavior.AllowGet);
}

$(document).ready(function () {
 //Call GetDisabledDates in the controller, passing id
 $.getJSON("GetDisabledDates", { id: "identifier" },
 function(data) {
 //write date values to hidden field for retrieval later.
 //and to ensure we only have to call server side method once. $('#hiddenDates').val(data.disabledDatesArray); });

 function IsDateAvailable(date) {
 //we have to pad the date, to ensure we can compare with the dates we retrieve from serverside.
 var dmy = padDate(date.getDate()) + "/" + padDate(date.getMonth()+1) + "/" + date.getFullYear();
 //remove dates in array from datepicker. if (IsDateInUnavailableList(dmy)) {
 //date exists in list of those not allowed. return [false,"","Unavailable"]; } else { return [true,"","Available"]; } }

 //pad out dates to allow comparison, 1/1/2012 will become 01/01/2012
 function padDate(i) { return (i < 10) ? "0" + i : "" + i; }
 //define datepicker
$("#datepicker").datepicker({ dateFormat: 'dd/mm/yy', minDate: 0, beforeShowDay: IsDateAvailable });
EnableOrDisableSaveButton();


$("#datepicker").change(function () {
            EnableOrDisableSaveButton();
        });



 function IsDateInUnavailableList(date) {
 var dateValues = $("#hiddenDates").val();
 //convert back into an array.
 var dateArray = dateValues.split(",");
 //check date against dates in array
 if ($.inArray(date, dateArray) < 0) { return false; } else { return true; } }

 // Function to enable or Disable the Save Button
 function EnableOrDisableSaveButton() {

 var date = $('#datepicker').val();
 // Now enable the button if the above two values or not empty
 if (date != "") {
 //prevent save button click if date selected in list of disallowed dates.
 if (IsDateInUnavailableList(date)) { $("#Save").attr("disabled", true); }
 else {
 $("#Save").attr("disabled", false); } }
 else {
 $("#Save").attr("disabled", true); } }

 //hidden field to store date values.
<input id="hiddenDates" name="hiddenDates" style="display: none;" />

//datepicker
@Html.TextBoxFor(m => m.Date, new { id = "datepicker", @maxlength = 10, style = "width:65px" })

<input id="Save" title="Click here to save" type="submit" value="Save" />
